Hi there everyone, i just installed ubuntu 10.10 last night, iam a new user with almost no experince with it...

Anyway i was having problems installing it cuz i was using capital alphabets in the user name, when i figured that out i already went in to installing beside an os instead of manual assignments.

So i knew the sda5 (partition) was my D drive in windows which i emptied to install ubuntu.

SO in installing beside os mode i had two drives i am sure one was D drive and the other was E drive.
C drive has win7 installed.
So i selected D(sda5) only and after installation i am no longer able to have access to windows 7 and it show 3gb used out of 1tb hard drive, which seems like it formatted the whole drive...
So is there something that i did wrong or something else cuz i no longer can see any data on the drive.
BTW i selected D drive which specifically said 150Gb not 1TB.
I really want my data back

Thx for ur help guys, the 320gb hd is my backup which is external. and as for the main drive
it is empty and i just removed ubuntu and installed win7 and there is no data. data recovery doesnt help much either so i just left ubuntu cuz it wasnt a good experince. So now
I just installed Vmware and installed ubuntu in there but havent used it yet though

I did actually do that like 5 times before and the installation wouldnt continue then i realized it was the username written in capital but till i realized i had already selected install with an os mode.
